Question

An ideal gas is enclosed in container. Upon heating, which property of the gas doesn’t change? A) Volume B) Pressure C) Average speed of the molecules. D) The rate of collision of the molecules with each other

Answer 1

(A) Volume does not change.

Explanation:

As gas is contained in a container and it is heated,

its volume remains unchanged but temperature increases causing increase in pressure

Hence (B) Pressure increases, (C) as temperature increases average speed of molecules too increases and (D) their rate of collision with each other too increases

Only (A) Volume does not change.
